| Abstract: |
| 【Objective】 Straw, organic fertilizer, biochar, and many other organic materials are widely used in agricultural production. Improving soil structure is one of its main effects. On this basis, quantitative evaluation of improvement effect has become one of the research hotspots at home and abroad. 【Method】This paper summarized and commented on the improvement effects of different organic materials on soil structure and their quantitative evaluation methods. 【Result】In low-temperature and arid areas, organic fertilizer and polyacrylamide have a better improvement effect on soil structure, while in areas with changeable climate and high temperature and humidity, the improvement effect of straw is better. Biochar is suitable for improving the structure of coarse soil, while woody peat is suitable for improving the structure of fine soil. In order to quantitatively evaluate the influence of organic amendments on soil structure characteristics in a multi-scale, the non-destructive acquisition technology of soil undisturbed structure and the corresponding digital image processing method have become the main research means at present and in the future. 【Conclusion】 In the future research, we should reasonably select improved materials according to the physical and chemical properties of soil, optimize the soil physical structure of each scale through multi-disciplinary intersection, and look forward to the new methods of studying soil structure. |
